architectures GNU libc is known to run *at some time*. This does not
mean that it still can be compiled and run on them in the moment.

+[Q8] ``I expect GNU libc to be 100% source code compatible with
+ the old Linux based GNU libc. Why isn't it like this?''
+
+[A8] {DMT} Not every extension in Linux libc's history was well
+thought. In fact it had a lot of problems with standard compliance
+and cleanliness. With the introduction of a new version number these
+errors now can be corrected. The following list shows a list of the
+know source code incompatibilities.
+
+* _GNU_SOURCE: glibc does not automatically define _GNU_SOURCE. Thus,
+ if a program depends on GNU extensions, it is necessary
+ to compile it with C compiler option -D_GNU_SOURCE. This difference
+ normally mainfests itself in the form of missing prototypes and/or
+ data type definitions. Thus, if you get such errors, the first thing you
+ should do is grep the header files in /usr/include and /usr/include/sys
+ to check whether the functions are really missing or whether it is
+ just necessary to add a define of _GNU_SOURCE. Similar comments apply
+ to _BSD_SOURCE, _POSIX_SOURCE, _SVID_SOURCE etc (see
+ /usr/include/features.h).
+
+* reboot(): GNU libc sanitizes the interface of reboot() to be more
+ compatible with the interface used on other OSes. In particular,
+ reboot() as implemented in glibc takes just one argument. This argument
+ corresponds to the third argument of the Linux reboot system call.
+ That is, a call of the form reboot(a, b, c) needs to be changed into
+ reboot(c).
+
+* errno: If a program uses variable "errno", then it _must_ include header
+ file <errno.h>. The old libc often (erroneously) declared this variable
+ implicitly as a side-effect of including other libc header files. glibc
+ is careful to avoid such namespace pollution, which, in turn, means that
+ you really need to include the header files that you depend on. This
+ difference normally manifests itself in the form of the compiler
+ complaining about the references of the undeclared symbol "errno".
+
+* Linux-specific syscalls: All Linux system calls now have appropriate
+ library wrappers and corresponding declarations in various header files.
+ This is because the syscall() macro that was traditionally used to
+ work around missing syscall wrappers are inherently non-portable and
+ error-prone. The following tables lists all the new syscall stubs,
+ the header-file declaring their interface and the system call name.
+
+ syscall name: wrapper name: declaring header file:
+ ------------- ------------- ----------------------
+ bdflush bdflush <unistd.h>
+ create_module create_module <sys/module.h>
+ delete_module delete_module <sys/module.h>
+ get_kernel_syms get_kernel_syms <sys/module.h>
+ init_module init_module <sys/module.h>
+ syslog ksyslog_ctl <unistd.h>
+
+ To get the Linux-specific declarations in <unistd.h>, you'll need
+ to define C pre-processor macro _LINUX_SOURCE during compilation.
